Image Compressor, Converter & Resizer
Compress, resize, and convert images directly in your browser. All processing stays on your device – nothing is uploaded.
What is image compression and why use it?
Image compression reduces the file size of an image without significantly affecting its visual quality. This is essential for websites, email attachments, social media, and saving storage space – all while maintaining a professional appearance.
Common use cases
- Website performance: Smaller images load faster, improving user experience and SEO rankings.
- Email attachments: Many email servers have file size limits; compression ensures your images fit.
- Social media: Platforms often compress uploaded images anyway – doing it yourself gives you control.
- Storage: Compress batches of photos to save space on your device or cloud storage.
How compression works
Our tool uses lossy compression (adjustable via the quality slider) to reduce file size by discarding some image data. Higher quality = larger file, lower quality = smaller file. You can also convert between formats – for example, converting PNG to JPEG often reduces size significantly.
All processing happens in your browser – your images never leave your device.
